PAUL L. HANSEN, OF PROVIDENCE, RHODE ISLAND.

BRACELET.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed September 30, 1907. Serial No. 395,116.

To all whom it may concern:

Be it known that I, PAUL L. HANSEN, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in Bracelets, ofwhich the following is a specification.

This invention has reference to an improvement in bracelets and moreparticularly to an improvement in expansible bracelets composed of aplurality of spring actuated units.

The object of my invention is .to improve the construction of anexpansible bracelet, whereby the spring units forming the bracelet aresimplified and strengthened and a more durable and flexible braceletconstructed than has heretofore been done.

A further object of my invention is to decrease the cost ofmanufacturing expansible bracelets composed of a plurality of springactuated units.

My invention consists in the peculiar and novel construction of anexpansible bracelet composed of a plurality of spring actuated units,said units having details of construction, as will be more fully setforth hereinafter and claimed.

Figure 1 is an edge View of an expansible bracelet composed of aplurality of my improved spring actuated units and showing the braceletin the contractedor normal position. Fig. 2 is an enlarged detailsectional view of two units taken on line 2 2 of Fig. 1 looking towardthe face and showing the units in the closed or contracted position.Fig. 3 is an enlarged detail sectional view similar to Fig. 2, showingthe units in the expanded position. Fig. 4 is an enlarged detailsectional view taken on line 4 4 of Fig. 3, showing the units in theirexpanded position. Fig. 5 is an enlarged view of the shell looking intothe interior of the same. Fig. 6 is an enlarged side view of the shell,showing the apertures in the side for the connecting link. Fig. 7 is anenlarged view of the back late looking at the outside of the same. Flg.8 is an enlarged edge view of the back plate, and Fig. 9 is an enlargedface view of a connecting link and actuating spring.

In the drawings, Fig. 1 illustrates an expansible bracelet composed of aplurality of spring actuated units a a, each unit a consisting of ashell I), a connecting link 0, a coiled actuating spring (1 on the linkand a back plate e. The shell ais stamped up from sheet metal to form arectangular box having the bottom 10 which forms the face'of thebracelet, the ends 11 11-, and the sides 12 12 in which are twoapertures 13 13 for the connecting link 0, as shown in Figs. 5 and 6.

The connecting link a is formed from Wire bent U shape to form thesemi-circular closed end 14 and the straight arms 15 15, as shown inFig. 9. After a connecting link 0 is inserted through the apertures 1313 in the sides of two adjoining shells the ends of the arms 15 15 ofthe connecting link are bent (by the use of a suitable tool) toward eachother to form the L-shaped ends 16 16 on the arms, as shown in Figs. 2and 3.

The coiled actuating spring (1 is coiled around and held in itsoperative position on the connecting link 0 with the ends of the springextending out onto the arms of the link, as shown in Fig. 1.

The back plate 6 is stamped up from sheet metal and has a raised centralpanel 17 forming a fiat annular lip 18 shaped to fit into the interiorof the shell I).

In assembling the units to form a bracelet, a connecting link 0 isplaced in position, the arms 15 15 of the link inserted through theapertures 13 13 in the adjacent sides 12 12 of two adjoining shells b b.and the ends of the arms bent toward each other to form the L- shapedends 16 16 on the arms. This brings the ends of the coiled actuatingspring (1 into engagement with the inner face of the side of a shell I)and the L-shaped ends 16 16 of the connecting link a into engagementwith the inner face of the adjacent side of the adjoining shell I), asshown in Fig. 2. The back 6 is now placed in the shell I) and secured byrolling the edge of the shell over the lip 18 on the back, as shown inFig. 4. These operations are repeated as many times as there are unitsin the bracelet. The bracelet can now be expanded by pulling the unitsapart against the tension of the coiled actuating springs d d on theconnecting links 0 c, as shown in Fig. 3. When released the units assumetheir normal or contracted position, as shown in Fig. 2, through thetension of the coiled actuating springs d.

It is evident that the shell I) could have any design or configurationdesired without materially affecting the spirit of my invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent;-

1. A bracelet composed of a plurality of units each consisting of ashell, a U-shaped link connecting tWo adjoining shells and a coiledspring surrounding the U-shaped portion of the connecting link intheshell.-

2. A bracelet composed of a plurality of units each consisting of ashell having apertures in its sides, a U-shaped connecting link the armsof Which extend through the apertures on the sides of tWo adjoiningshells, a coiled spring on the connecting link engaging With the side ofa shell, and means for securing the ends of the connecting link in thead joining shell, whereby the units are held in their normal orcontracted position under spring tension.

3. In a bracelet, a U-shaped connecting link 0 constructed to have theclosed end 14 and the arms 15 15 With the bent-over ends 16 16, and acoiled spring at surrounding the U-shaped portion of the connectinglink, as 2 described.

4. A bracelet composed of a plurality of spring actuated units a a eachunit a consisting of a shell b, a U-shaped connecting link 0,

a coiled actuating spring (1 surrounding the 2 U-shaped portion of theconnecting link and a back plate 6, as described.

In testimony whereof I have signed-my name to this specification in thepresence of two subscribing Witnesses.
